Total iron binding capacity
Name total_iron_binding_capacity_gprd
Chapter Diseases of the blood/Haematinics
Definition
Iron-carrying capacity of the blood, to be interpreted in conjunction with serum iron. The correct units are micromol/L, but the distribution of values with units mmol/L are similar, which suggests that these units should actually be micromol/L.

Values of 0 or >= 1000 are considered to be errors.
